[Alteration in quality of life in anorexia nervosa and improvement under treatment: validation of a new questionnaire, the QUAVIAM]. / Altération de la qualité de vie dans l'anorexie mentale et amélioration sous traitement : validation d'un nouveau questionnaire, le QUAVIAM.

Anorexia nervosa (AN) is a chronic and often severe eating disorder, which could have a serious impact on various life domains. AN may lead to physical, mental, behavioural and socioprofessional impairment. Thus, one could expect a poor quality of life (QoL) in AN patients. QoL is certainly a key factor to provide quantitative measurement of treatment efficacy that will facilitate clinical decision-making and treatment planning. Despite that QoL was rarely prospectively analyzed in AN patients, one could conclude that AN patients showed reduced QoL, as compared to normal controls and other psychiatric-disordered patients. It seems that mental health components of QoL are more impaired than the physical ones in AN patients, who showed a modest impact in the physical domain. Thus, our aim was to analyse the QoL using a new, French, questionnaire, the QUAVIAM (qualité de vie dans l'anorexie mentale). After a bibliography research (including EDE, EDI, SF-36, QOL.ED), the choice of 12 themes, regrouped in six scores, was made by three eating disorder specialists and two recovered patients. For each score, 10 to 15 questions were written by the experts, and then corrections and validation were made by the five experts and 21 patients. After this, we prospectively determined the reproducibility (3 days interval), the specificity, and the sensitivity for short-term change in patients exhibiting an "active" AN (n=54, mean age: 31 ± 9 yrs, mean BMI: 14.1 ± 2.8 kg/m(2), AN duration: 2.6 ± 1.9 yrs), and again after cognitive behavioral therapy (CBT). We also analyzed the QUAVIAM score and subscores in 48 recovering patients and in 56 subjects without eating disorder. The QUAVIAM final version (61 questions) was collected in 76 patients and the 56 healthy controls matched for sex and age. Its reproducibility was 91% (intra-questionnaire) and 94% (inter-questionnaire), its specificity 98% (versus controls; P<0.0001) and its sensitivity 99%. The QUAVIAM global score of the AN patients was more impaired (389 ± 87) than that of the recovering patients (157 ± 82) and the normal controls (89 ± 49; P<0.0001). Each of the six subscores was higher (more altered) in active AN than in recovering AN patients and in normal subjects: the somatic, the psychological, the hedonic, the socioprofessional, the affective and the TCA-related ones (P<0.001 for each comparison). The QUAVIAM global score and its subscores were significantly improved (decreased) by the 3-month CBT: 385 ± 25 before and 189 ± 30 after CBT (P<0.0001). The changes were observed for all the subscales (P<0.0001). The somatic subscore did not decrease less than the other subscores. Thus, the present study permits proposing the QUAVIAM for analysis of physical, mental, behavioural and socioprofessional impairment or improvements in AN patients.

[Triggers of bulimia and compulsion attacks: validation of the "Start" questionnaire]. / Les inducteurs des crises dans la boulimie et la compulsion : validation du questionnaire « Start ¼

AIM: There are few published studies on the triggers of binge eating in anorexia nervosa of binge/purging subtype (BPAN), bulimia nervosa (BN) and binge eating disorder (BED). PATIENTS AND METHODS: We validated in 29 patients (10 BPAN, 10 BN and 9 BED) the perspicuity, the clarity and the intra- (doubles) and inter- (test-retest) reproducibility of a 24-item Start questionnaire on the triggers of binge eating. Then the Start questionnaire was administered to 176 patients (65 BPAN, 62 BN and 59 BED patients) being 27.5+9.1 yr old, having 15+9 binge eating (BE) episodes/week, with a mean binge duration of 1 hr 36min (+ 38min)/day. RESULTS: BE episodes occurred mainly during the second part of the day: afternoon after work (67% of the patients), "tea" time (55%), evening after dinner (42%) and at night (22%). The principal place for BE episodes was at home (96%). The BED patients avoided binges at the parents' home (89%) more often than the BPAN (62%, P<0.02). The binges occurred mainly in the living room (44%), in the kitchen (43%), and less in the bedroom (31%). Hunger pangs seemed to be a trigger of binges in 31% of the patients, and a stronger trigger in BED (42%) than in the BPAN and BN patients (24%; P=0.04). Binge eating episodes could occur despite a high satiety level (just after lunch or dinner) in 29% of the BN and in 16% of the BED patients (P<0.02). Concerning food, the major triggers were high energy-density food (77%) and comfort food (60%), such as chocolate, cakes, bread and pasta. The food consumed for binge episodes (in-binge food) was more often a strong trigger than the other food (not used for binges): olfaction (19% versus 10%), sight (52% versus 25%) and placing in the mouth (71% versus 26%; P<0.02 for all, in the 3 groups). Being tired could be a strong trigger in 37% of the patients, but "being aroused" in the other 38 % of the patients. Stressful events (65%), anxiety (74%), "being under pressure" or irritated (51% and 55%) were of course major triggers in a majority of the patients, as well as sadness (61%), feeling of powerlessness (62%), inefficiency (73%) and depressive state (71%). Flashback from traumatism (sexual trauma in 17% of the patients) was a strong trigger of binges more often in BPAN and BED (44%) than in BN (23%; P<0.05). The binge eating was painful (and "not at all a pleasure") in 69% of the patients, but could also be a relaxing behavior in 31% of the patients, more often in the BED (43%) than in the BPAN patients (20%; P<0.05). The binge eating behavior was quoted as obsessive in 63% of BPAN, 92% of BN and only 34% of BED patients (P<0.001). The patients said that they were unable to avoid the binge (76% of the patients), more often in BPAN and BN than in BED patients (P<0.01). As a whole, 62% of BPAN, 89% of BN and only 4 % of BED patients (P<0.05) were unable to avoid purging (vomiting). In 12% of the cases, there was a pleasure felt when binging. For the other patients, shame, filth and incapacity were the feelings related to binges in 58% of the BPAN, 45% of BN and 43% of BED patients (P<0.04). The global score of addiction (zero=not addicted, 10=very addicted) was 8.56+1.2 in BPAN, 8.42+1.5 in BN and 6.74+1.1 in BED patients (NS between BPAN and BN; P<0.01 between BPAN and BN on the one hand and BED on the other). CONCLUSION: The present study has demonstrated the usefulness of the Start questionnaire. It also evidences the key role of intrinsic factors, both metabolic and emotional, as strong triggers for binge eating episodes in BPAN, BN and BED. It has also demonstrated the role of environmental determinants.

Outcome in AN adult patients: a 13-year follow-up in 484 patients.

BACKGROUND: To study the long-term prognosis of anorexia nervosa (AN), 484 adult AN patients were followed on a mean duration of 13 years. RESULTS: The mortality rate was 1.2%. Eight factors were linked to the lack of recovery at 2 years: low BMI at discharge, low energy and fat intakes, high drive for excessive exercising, high score for perfectionism, for interpersonal distrust and for anxiety, use of tube-feeding and adhesion to treatment (P<0.02). Four factors explained the risk of the binge/purging form at 2 years: having had binge-eating disorder and overweight before AN, having had purging episodes within the first 2 years of AN; having had very high energy intakes through meals and being not treated by tube-feeding. During the 13-year follow-up, very few binge/purging patients turned out to have the restrictive form. Two main factors explained 67% of the variance of menses recovery: having a BMI>18.5 kg/m(2); and having no physical hyperactivity. The recovery rate increased with the elapsing of relapse-free time (P=0.02). After a 13.5-year follow-up, 292 out of the 484 patients were recovered (60.3%), 25.8% had a relatively good outcome, 6.4% a bad outcome and 6.4% a severe outcome. Very few factors were identified as predictors of a good outcome (binge-eating/purging subtype, personality disorder).
